I don't know, but I wouldn't be surprised if we didn't. IIUC address spaces are used for heterogeneous computing to identify, e.g., which memory lives on a GPU vs the main memory, and in that case the code for the GPU would be generated by a different backend anyway, so the distinction is probably less useful?
